In order to investigate the micro tangential sliding characteristics of rough surfaces,a nite element analysis(FEA)model with the shape of the rotary parabola was proposed to simulate tangential sliding of asperities.The model can deal with the deformation mechanism of elastic,elastic-plastic and plastic.The effects of the tangential and normal distance on the tangential and normal force were discussed in the whole tangential sliding process.Based on the results,the fitting formula of the dimensionless variation of the load was presented.Using the Kogut's elastic-plastic model named KE model,the shoulder to shoulder contact model was deduced to explain the sliding characteristics.It is shown that the KE shoulder to shoulder contact model is valid for the case of small deformations.However,for the large sliding distance,the plastic flow along the slip direction increases with the increasing sliding distance,and the errors between KE model and the FEA model become larger.In addition,the maximum,the minimum and the mean value of the loads have obvious change trends.The simulating and theoretical research of the sliding characteristics between asperities provides a foundation for the study of the sliding characteristics between rough surfaces.
